An Article 4 direction is a decision by a local authority to remove permitted development rights for specific types of work within a defined area, so something that would normally need no planning permission does need it.
What it typically covers
Replacing windows or doors. Painting or rendering a front elevation. Removing front boundary walls or railings. Roof alterations. Adding satellite dishes.
They are common in conservation areas and on estates where a consistent appearance is protected, but they can be applied anywhere and are not limited to designated areas.
Why it catches people
Because nothing about your house tells you one exists. It is not on the deeds and not visible from the street. Homeowners routinely replace windows in good faith and discover afterwards that permission was needed.
Neighbours are not a guide either, a neighbouring property may sit just outside the boundary of the direction.
How to check
Ask the local planning authority, giving your address. It is a quick enquiry and it is the only reliable way to know.
Do this before ordering anything made to measure. Windows in particular are non-returnable, and reinstatement after enforcement is expensive.
